It's been widely reported that Kim Kardashian and Rob Kardashian were at odds over his failure to achieve weight loss.

Prior to her wedding ceremony in France, in fact, Rob Kardashian walked out of the pre-wedding party after he was allegedly insulted by Kanye West's wife for unsuccessfully dropping his weight just like he promised her.

Months ago, Rob Kardashian also Instagrammed a photo of Rosamund Pike in the movie "Gone Girl" and comparing her character to Kim Kardashian whom he described as a b**ch.

But on Aug. 14, a pregnant Kim Kardashian revealed in a Twitter post that she went on a bonding time with Rob Kardashian who has been hiding at Khloe Kardashian's house after failing to lose some of his excess weight.

Kanye West's wife tweeted, "Just went on the hardest hike ever today with @robkardashian."

The tweet was reposted by her brother who said, "GOOD work gurrrrrrllllll‼️."

Ryan Seacrest, executive producer of "Keeping Up with the Kardashians," also commented, "Which trail?? Need a new one."

One of her followers commented, "yay I hope Rob is in the process of changing his life around. I love you both so much!!!"

Another said, "That is great you two are spending time together. Good to hear. (H)ope more family time is in the near future."

"GOOD keep working with him. He needs to get happy again. Happy is a hot look," another advised.

However, one fan wasn't all convinced as she said, "@KimKardashian @robkardashian @Slutkirk i sense a new weight loss/sobriety reality show lol."

Rob Kardashian's weight loss problem has reportedly been causing tension on the family, particularly with momager Kris Jenner and Kim Kardashian.

In one of the episodes of "KUWTK," a crying Kris Jenner said, "I'm not a therapist. I'm not a doctor, but I do know that we've got all of the resources in the world, and yet he doesn't access."
